A man charged in the slayings of a wealthy family and their housekeeper inside a Washington mansion is due in court for a preliminary hearing.

Police say Daron Wint held the Savopoulos family captive for up to 18 hours inside their home in May before he was paid a $40,000 ransom. After that, police say he stabbed and beat the victims to death and set the house on fire. He was captured a week later.

Savvas Savopoulos was the CEO of American Iron Works, a construction-materials supplier. He was killed along with his wife, their 10-year-old son and a housekeeper. The 34-year-old Wint is a welder who once worked for Savopoulous' company.

Thursday's hearing will provide Wint's new attorney with his first opportunity to question the evidence against his client.
